  • How to select product that have the maximum price of each category?

    - by kimleng
    The below is my table that has the item such as: ProductId ProductName Category Price 1 Tiger Beer $12.00 2 ABC Beer $13.99 3 Anchor Beer $9.00 4 Apolo Wine $10.88 5 Randonal Wine $18.90 6 Wisky Wine $30.19 7 Coca Beverage $2.00 8 Sting Beverage $5.00 9 Spy Beverage $4.00 10 Angkor Beer $12.88 And I suppose that I have only three category in this table (I can have a lot of category in this table). And I want to show the maximum product's price of each category in this table.

  • How to close all, or only some, tabs in Safari using AppleScript?

    - by Form
    I have made a very simple AppleScript to close all tabs in Safari. The problem is, it works, but not completely. The problem is that only a couple of tabs are closed. Here's the code: tell application "Safari" repeat with aWindow in windows repeat with aTab in tabs of aWindow if [some condition is encountered] then aTab close end if end repeat end repeat end tell I've also tried this script: tell application "Safari" repeat with i from 0 to the number of items in windows set aWindow to item i of windows repeat with j from 0 to the number of tabs in aWindow set aTab to item j of tabs of aWindow if [some condition is encountered] then aTab close end if end repeat end repeat end tell ... but it does not work either (same behavior). I tried that on my system (MacBook Pro jan 2008), as well as on a Mac Pro G5 under Tiger and the script fails on both, albeit with a much less descriptive error on Tiger. Running the script a few times closes a few tab each time until none is left, but always fails with the same error after closing a few tabs. Under Leopard I get an out of bounds error. Since I am using fast enumeration (not using "repeat from 0 to number of items in windows") I don't see how I can get an out of bounds error with this... My goal is to use the Cocoa Scripting Bridge to close tabs in Safari from my Objective-C Cocoa application but the Scripting Bridge fails in the same manner. The non-deletable tabs show as NULL in the Xcode debugger, while the other tabs are valid objects from which I can get values back (such as their title). In fact I tried with the Scripting Bridge first then told myself why not try this directly in AppleScript and I was surprised to see the same results. I must have a glaring omission or something in there... (seems like a bug in Safari AppleScript support to me... :S) I've used repeat loops and Obj-C 2.0 fast enumeration to iterate through collections before with zero problems, so I really don't see what's wrong here. Anyone can help? Thanks in advance!

  • NSBorderlessWindow not responding to CMD-W/CMD-M

    - by Sean
    I have an NSBorderlessWindow subclass of NSWindow with a transparent and non-opaque background (so it's non-rectangular in appearance). I've added my own buttons to function as the close and minimize buttons when I click them, but for some reason the window will not respond to CMD-W or CMD-M like a normal one does. I have my NSWindow subclass set to return YES to canBecomeKeyWindow and canBecomeMainWindow. My NIB still has all the standard menu items in it that are there when you create a new project - including the "Minimize" item in the Window menu with the default shortcut CMD-M defined. It's hooked up to send performMiniaturize: to the first responder. However it is not enabled when the app is run, so it seems like it must be asking the window if it can minimize and the window says no or something. (I'm still very new to OSX/Cocoa.) What am I missing? Also, and maybe this is related, my borderless window has a shadow enabled - but unlike a normal titled window, when I make my window the active/front window by clicking on it, the shadow doesn't change. Normally an OSX focused window has a slightly larger/darker shadow to make it stand out more but mine never changes the shadow. It's like I'm missing something to make the OS treat this window as a real/normal/main window or something and as a result I lose the shadow change and functioning CMD-W/CMD-M.

  • JVM terminates when launching eclipse with J2SE 6.0 on mac os x (need J2SE 6.0 for Oracle enterprise

    - by rooban bajwa
    I know my issue has party been addressed at this link http://stackoverflow.com/questions/245803/jvm-terminates-when-launching-eclipse-mat-on-mac-os-with-j2se-60 but it was a year+ ago.. plus the link that's provided in there http://landonf.bikemonkey.org/static/soylatte/ does not seem to be alive (i mean the download section on that link no longer provide the 32-bit port of j2se 6.0 for mac osx 10.5) I am trying to run eclipse 3.5 on mac OSX 10.5. It works fine with J2SE 5.0. But when I installed the Oracle enterprise pack for eclipse - it requires to start eclipse with J2SE 6.0 JVM otherwise it will get disabled. Here's the exact message I get from it - "You are running Eclipse on Java VM version: 1.5.0_22 Oracle Enterprise Pack for Eclipse requires Java version 6 or higher. Click next to configure a compatible Java VM." It asks me to point to J2SE 6.0 JVM, when I do that (i.e point it to "/System/Library/Frameworks/JavaVM.framework/Versions/1.6.0/Home") , it asks to restart eclipse , when I do that, eclipse just bombs .. with JVM terminated error .. SO I need to start eclipse with J2SE 6.0 JVM but eclipse needs carbon which is only available in 32 bits and hence I cann't start eclipse with J2SE 6.0 JVM which is only available in 64bit mode from mac. And the site providing 32 bit port of J2SE 6.0 JVM does not seem to be active anymore.. Can someone help me on this issue, Thanks in advance,

  • Saving "heavy" figure to PDF in MATLAB - rendering problem

    - by yuk
    I generate a figure in MATLAB with lot amount of points (100000+) and want to save it into a PDF file. With zbuffer or painters renderer I've got very large and slowly opened file (over 4 Mb) - all points are in vector format. Using OpenGL renderer rasterize the figure in PDF, ok for the plot, but not good for text labels. The file size is about 150 Kb. Try this simplified code, for example: x=linspace(1,10,100000); y=sin(x)+randn(size(x)); plot(x,y,'.') set(gcf,'Renderer','zbuffer') print -dpdf -r300 testpdf_zb set(gcf,'Renderer','painters') print -dpdf -r300 testpdf_pa set(gcf,'Renderer','opengl') print -dpdf -r300 testpdf_op The actual figure is much more complex with several axes and different types of plots. Is there a way to rasterize the figure, but keep text labels as vectors? Another problem with OpenGL is that is does not work in terminal mode (-nosplash -nodesktop) under Mac OSX. Looks like OpenGL is not supported. I have to use terminal mode for automation. The MATLAB version I run is 2007b. Mac OSX server 10.4.

  • how do I make a portable isnan/isinf function.

    - by monkeyking
    I've been using isinf,isnan functions on linux platforms which worked perfectly. But this didn't work on osx, so I decided to use std::isinf std::isnan which works on both linux and osx. But the intel compiler doesn't recognize it, and I guess its a bug in the intel compiler according to http://software.intel.com/en-us/forums/showthread.php?t=64188 So now I just want to avoid the hassle and define my own isinf,isnan implementation. Does anyone know how this could be done Thanks edit: I ended up doing this in my sourcecode for making isinf/isnan working #include <iostream> #include <cmath> #ifdef __INTEL_COMPILER #include <mathimf.h> #endif int isnan_local(double x) { #ifdef __INTEL_COMPILER return isnan(x); #else return std::isnan(x); #endif } int isinf_local(double x) { #ifdef __INTEL_COMPILER return isinf(x); #else return std::isinf(x); #endif } int myChk(double a){ std::cerr<<"val is: "<<a <<"\t"; if(isnan_local(a)) std::cerr<<"program says isnan"; if(isinf_local(a)) std::cerr<<"program says isinf"; std::cerr<<"\n"; return 0; } int main(){ double a = 0; myChk(a); myChk(log(a)); myChk(-log(a)); myChk(0/log(a)); myChk(log(a)/log(a)); return 0; }

  • Best support now on windows: Mercurial or Git?

    - by mamcx
    I want to change my current subversion setup to Mercurial or Git. I read about the two and I have a conflicted view about how well they work on windows. Alot of pages say Git is sub-par on windows, slow and badly integrated. And almost everyone say Mercurial is better. But some say Git now is better and Mercurial is behind. I check the screenshots of TortoiseHG and TortoiseGIT and the mercurial one look "worse"... but maybe is just crappy screenshots? I read about the two, prefer the command-line interface of Mercurial, but seriously, I don't pretend to touch the command line. And if one of the two is a real improvenment to SVN, I don't have to do that (In SVN is necesary go to the metal because something need fix). In SVN I have issues when commit or get code made on OSX (I code on Windows, OSX, Solaris. Mainly windows). So I hope don't get that issues again (I mean, failure to commit to the repo). I have a small repository, doing solo.

  • Excessive httpd processes to stack up on my Rails + Apache2 + Passenger production setup?

    - by LeoAlmighty
    I have a Rails + Apache2 + Postgres + Passenger application running in production mode in OSX Snow Leopard. The application serves as a data warehouse for another application in the cloud so I'm constantly getting API calls to my OSX production build. After a recent reboot, I'm finding a ton of httpd processes stacking up and eventually requiring an apache reboot. I haven't changed any settings, everything was running fine before.

  • Subversion unable to merge changes when using Dreamweaver

    - by neilc
    I've got a project running and we're using SVN as the version control. There are 3 devs on it. Dev1 = OSX + Textmate Dev2 = Windows 7 + Dreamweaver (plus tortoise svn) Dev3 = OSX + Coda Case 1 (expected): Dev1 and dev3 work on a file called signup.php. They work on different parts of the file. Dev1 commits it and dev3 updates their copy. signup.php is merged as expected. All good. Case 2 (not expected): Dev1 and dev2 work on a file called signup.php. They work on different parts of the file. Dev1 commits it and dev2 updates their copy. signup.php is always in conflict even though different parts of the file are worked on. This is not the expected behaviour experienced by dev1 and dev3. This works boths ways and each time dev1 updates dev2's changes he gets conflicts too. But never with dev3. Could this be down the way Dreamweaver is saving files ? Perhaps character encoding. We are all working in UTF8. These constant and unnecessary conflicts are becoming a massive distraction. Help !

  • Snow Leopard tzdata

    - by pgb
    I live in Argentina, and our DST rules change often. So often, that major OS' tend to ship with an old version of tzdata DBs. In the past, I successfully updated the time zone databases in Tiger and Leopard. Today, however, when trying to update it in Snow Leopard, it did not work. Not only it failed, but now even after I reverted my changes, there seems to be some "cache" where the time zone information was retained. The files I updated (and reverted) are located at: /usr/share/zoneinfo and /usr/share/icu. To update those, I grabbed Apple's source code for ICU and recompiled it's database using the latest tzdata file (2010b). Then, I recompiled the tzinfo by running zic, and copied all the files to the system folders. Does anyone have experience dealing with Snow Leopard's timezone DB and can help? Thank you.

  • Which file system to use for portable hard drive shared among different operating systems?

    - by Jonathon Watney
    Something similar has been asked already but my criteria is a little different. I need to share a portable hard drive (USB/Firewire) between Mac OSX, Linux and Windows XP systems where the files being shared are sometimes 4GB. Is there a file system that is available out of the box on all these operating systems that support this and allows read/write access? If not, what's the next best solution in terms of installing additional software on these operating systems?

  • Mac OS X Server Open Directory does not push Software Update settings to clients

    - by joxl
    I have an Xserve G5 running Mac OS X Server 10.5.8 configured as an Open Directory master. I have also enabled and configured Software Update service on the machine. The SUS is configured to serve Tiger, Leopard and Snow Leopard clients (see http://discussions.apple.com/message.jspa?messageID=10297359#10297359) The clients bound to the OD are a variety of Mac's running OS X 10.4, 10.5 or 10.6. In Workgroup Manager, I have created 3 machine groups for each client OS. Each group is configured with a custom SUS URL, and the managed client computers are members accordingly (see http://discussions.apple.com/thread.jspa?messageID=10493154#10493154) My problem is that the server pushes the SUS settings to some of the client machines, but not all. When I first configured all this stuff on the server (a few weeks ago) I was closely monitoring a few of the client machines to confirm that they received the custom settings. I noticed that some of the clients (10.4/5/6 alike) seemed to get the settings immediately, others didn't show the new settings until after a reboot. As I said, results are mixed across OS's, but some clients will not "sync" at all. My immediate thought was to unbind/rebind the problematic machines. I did this on several client computers with no success. For example, today I was working on one of the Tiger clients. I noticed it was not pointed at my local SUS, so I checked the OD binding; it was fine. Just to be sure I unbound the machine. Next, I checked WM and confirmed the computer record was gone. I noticed the machine group still had a residual (broken?) member from the unbound client; I manually removed this. Finally, I re-bound the client to OD and re-added the machine to it's correct group in WM. Unfortunately, the client still pings apple's SUS for updates. Just to play it safe I rebooted the client, but to no avail, it will not see my local SUS. To confirm that there is nothing wrong with the server, or the client's connection to it, forcefully pointed the machine at my SUS: sudo defaults write /Library/Preferences/com.apple.SoftwareUpdate CatalogURL "$LOCAL_SUS_URL" and the machine successfully updated off my local server. Great, successful updates, but problem not solved. I've done exhaustive reading on discussions.apple.com (not saying I read everything, I'm just saying I have read a lot) without a good answer. The discouraging thing is that a lot of OD problems I've read about only result in the sysadmin completely reinstalling the server, or OD, or some other similarly heavy-handed operation. At this point, I am not willing to go that route. I still have hope that I can find the reason for this flaky behavior. If anyone can point me in a helpful direction it would be much appreciated. EDIT: Indeed, some files are being pushed to the client: # from client machine: $ sudo find /Library -type f -name com.apple.SoftwareUpdate.plist /Library/Managed Preferences/com.apple.SoftwareUpdate.plist /Library/Managed Preferences/username/com.apple.SoftwareUpdate.plist /Library/Preferences/com.apple.SoftwareUpdate.plist A few weeks ago, prior to my (previously mentioned) modifications, the SUS was still running "stock". Which meant it could not serve SL (10.6) machines. At that time, the Software Update settings were setup in WM under User Groups. This didn't make any sense because some users work on multiple machines with different OS's. Before creating Machine Groups in WM, I deleted all the SU settings from the User Group Preferences. This just makes the whole thing more confusing, because when I see a file here: /Library/Managed Preferences/username/com.apple.SoftwareUpdate.plist I assume it's still remaining from the "old" settings, because I wouldn't think a Machine Setting belongs there. Despite all the com.apple.SoftwareUpdate.plist hanging around under the Managed Preferences, why does the client machine still call home to Apple and not my SUS? # on client machine: $ date Tue Jan 25 17:01:46 EST 2011 $ softwareupdate --list Software Update Tool Copyright 2002-2005 Apple No new software available. switch terminals... # on server: $ tail -n1 /var/log/swupd/swupd_access_log 10.x.x.x - - [25/Jan/2011:15:54:29 -0500] XXXX POST "/cgi-bin/SoftwareUpdateServerStats" 200 13 ... Notice the date of the client softwareupdate and the latest access to the SUS server; the server never heard a peep from that client.

  • Best Practise: DNS and VPN (with private network IPs)

    - by ribx
    I am trying to find the best solution for my DNS problem. We are running several services in our company that you can reach only over VPN. Other services, that are reachable through the internet got the domain ... At the moment all services inside the VPN network go by .local... These have an VPN IP of the private network 192.168.252.0/24. Clients reach from Linux over OSX to Windows. I can think of 4 possibilities to implement a DNS infrastructure: Most common: an internal DNS Server, that is pushed by the VPN. But this has several drawbacks: your DNS responses are limited to the speed of the VPN Connection and your own DNS server. Because of very complex websites, this can increase the time for a page to load quite a lot. Also: we have several VPNs that are not connected to each other and all of them have their own DNS server. Several DNS servers locally. These have to be configured by hand. And you have to use some third party tool like dnsmasq. If you start a DNS request, you ask your locally running DNS server, which decides which server to ask for which domain name. One college of mine uses such a solution with this OSX (I am sorry, I don't remember the name of the application). You use your domain hoster. Most of them have APIs available to manipulate your DNS entries. So you could pull your private network informations to your domain hoster. I am not sure whether they all accept private network IPs. But I guess there will be some problems in the same way as in number 4. The one we currently use, because it's for us the most logical choice: we forward the sub domain *.local.. to our own public DNS Server. This works quite good for some public DNS Servers like Google. But most ISPs do not forward the answers. Or don't do that always. Like my ISP sends me a positive result of the a DNS request of a *.local.. domain only every 10th time I make a nslookup. (Can someone explain this?) Here the real Question: Is there another solution we were not thinking about? Or: What of these methods do you use?

  • Slow performance by PHP directory operations on virtual machine (Ubuntu libvirt)

    - by thonixx
    Some days ago I installed an Ubuntu server and two running virtual machines with libvirt. Everything works fine except one performance problem. Everytime when I call a PHP script with directory operations the operations are very slow and not performant. Here is an example: http://zother.white-tiger.ch/ And here you see an example without a directory operation and how fast it is: http://michaeltanner.ch/ It's all on the same virtual server. The virtual machine uses 6 cores (8 are available) and 7500 megabytes RAM (8 Gigabyte are available). The disk image format is qcow2. How can I improve the performance?

    I'm looking for a tool to sync my bookmarks locally, without uploading them to any website (like xmarks does.) Example: i currently use 1Password to sync my logins/passwords. They are not uploaded to any website. The program simply syncs between devices (Mac OSX, iPad, Windows) on the local network, without the need of any remote server/database. Now i'm looking for a tool that does (kind of) the same thing, for bookmarks.
